Brain is your personal AI OS — it scales you, your judgment, your taste, your craft, across every project and every inbox. You, amplified.
Most AI tools assume you'll wing it — figure out what to automate, which LLM to use, where the memory lives, how to keep your work organised. Brain doesn't. Six composing products give you a Chief of Staff to run your day, a Project Coach to discipline your LLM, and an AI Staff that handles the repeatable work — while you decide what gets built. ~60% off flagship cost while you're at it.
See the products →Each one stands on its own. Together they compose into a Brain that knows what you're working on, what's incoming, what's running, and what your team is doing.
Most "principles" pages are marketing. Ours are engineering commitments — promises baked into the architecture so we couldn't break them even if we wanted to.
The CLI runs on your machine. The desktop app runs on your machine. Even Nerrem Cloud is just a place to host your tenant — move it to a VPS, a Mac Mini, an air-gapped box. We've never had a "the servers are down" outage because there are no required servers.
Your master key is derived from a passphrase that never touches our infrastructure. We see encrypted bytes; you see your work. Export everything in standard formats whenever you want. "Trust us — we're encrypted" is for companies that don't show you the code.
Team Brain is a federation of personal Brains — not a shared workspace you all log into. Each member owns their data; the team layer is only what's chosen to be shared. Sync hub on Nerrem Cloud, on your hardware, or skip the central server entirely. Air-gapped, OSS-only deployments work.
Brain is commercial proprietary software. Our business model is selling a product that works — not harvesting what you do with it. We don't train on your data, fingerprint your installation, or analyse your usage. LLM calls route through Zero-Data-Retention endpoints. The only thing we measure is what's needed to bill — scoped, minimal, never re-sold. (core-brain may go OSS down the road; the products around it stay ours.)
